Weird decompilation issue with "gml_Object_blt_hoopbullet2_Collision_760"

[Grossley]

action_set_hspeed((-hspeed)) appears to have redundant parentheses. Check to see whether this is real or an error.

This is because Decompiler.ExpressionOne.cs#L40 always produces parentheses. An appropriate fix might be adding a ToStringNoParens method and invoking that in Decompiler.DirectFunctionCall.cs, similar to the change to that file in #1675.
